Introduction

After a bad experience with a Huanyang VFD, we subsequently integrated a Delta (TODO: get model) VFD. The integration was fairly straightforward as the two VFDs were very similar.

Wiring details

Wires from the control head

Wire	VFD Side	Control head side	Meaning
Gray	Sindle lock
Purple	REV	Direction switch reverse
Orange	FOR	Direction switch forward
Brown	ACM	Ground of speed POT and digital tach	Analog ground signal
Tan	10V	Top of speed POT	+10V reference for speed control
Pink	V0	+ signal of digital tach	Analog speed output to the digital tach
Red	+24V		+24V for latch circuit
Black	VI	Wiper of speed POT	Analog speed signal in
Blue	No Connection	latched ground	Intended to be a run enable signal

Wires from spindle lock

Spindle lock is normally closed, open when the spindle is locked

Wire	Use
Red	Gray signal wire to complete ground circuit.
Black	DCM

Wires from the Mesa card

Wire	Meaning
Orange	+ of the digital input
Orange/white	Ground of the digital input
Blue	+ of the isolated digital estop out
Blue/white	Ground of the digital estop out

The braking resistor is ~40 ohms.

This control panel was rewired to:

Use 24V DC relays for the latching enable circuit Use a different forward/reverse switch that provides independent normally open switches for forward and reverse Simplify the wiring for the analog speed input so that it was independent of the enable latch. This was needed as this drive has separate DC control and analog in grounds.

The wiring of the latch relay is currently not ideal as the wiring is way over-sided. Smaller wires with crimp terminals would greatly simplify it and make it more reliable.

02-00	0	1	TODO: confirm this is: Forward/reverse signals from the wired inputs
02-01	0	1	TODO: confirm this is: Analog speed in from the wired inputs

TODO: other tuning changes
